ENGINE.

To all whom it may concern.-

Be it known that I, ARTHUR J. PAIGE, a-

citizen of the United States, residing at Terre Haute, in the county of V lgo and State of Indiana, have invented certain new and useful Improvements in Engines,

of which the following is a specification.

The object of my invention is ,to produce a compact motor, preferably of the internalcombustion type, having a high power per unit of size and weight, and thereby especially suitable for use in automobiles, 620.,

although not limited to such use.

The accompanying drawings illustrate my invention. I

Figure 1- is a transverse section of an apparatus embodyin my invention in the form of an internal-com ustion engine, and Fig.2 a section on line 2 2 of Fig. 1. I

In the drawings, 10 indicates a main stationary casing which is preferably composed of two supplementary members mating ona medial plane at right angles to the axis of journal-bearings 11, formed therein. The main casing 10' is provided with an annular chamber 12, preferably circular in cross-section and communicating with the interior of casing 10 through a continuous slot 13, formed in the imier wall of said annular chamber. Mounted in the annular chamber 12 are expansion-chambers 14, 15, 16, and 17, as many of these chambers being provided as may be desired andeach of said chambers fitting the annular chamber 13 and being provided at its ends with packin -rings 18 of any wellknown form. In or er to further pack the expansionchambers within the annular chamber 13, packing-strips 19, arranged near the axial middles of the expansion-chambers and externally thereto, are provided, said packing-strips extending between the inner packing-rings 18 and interlocking with them, as shown. Each expansion-chamber is attached to an arm 20 of a spider 21, secured to a shaft 22, journaled in bearings 11. The spider 21 and arms 20 therefore rotate with the shaft 22, .and the arms 20 project through the groove 13 into the annular chamber 12. Reciprocably mounted in each of the expansion-chambers 14, 15, 16, and 17 is a piston 14, 15, 16, and 17,res pistons 14 and 16" being connecte to a pair of oppositely-extending arms 23, which arms are connected together and freely journaled upon shaft 22. Similarly pistons 15 and 17 Specification of Letters Patent. Application filed January 31, 1907. Serial Np. 355,098.

are connected to a pair of oppositely-extending arms 24, which are connected together and journaled freely upon shaft 22. Each 7 of arms 20 is connected to the adjacent arm 23 or 24 by a spring 25, which tends to draw said arms together, thus causing the piston connected to the corresponding arm 23 or 24 to, be moved within its expansion-chamber to its outward position. Arranged between each pair of arms 20' 24 is a two-armed cam 30, the arms of which are diametrically opposed, and each of these cams is carried by a planetary shaft 31, which is journaledina pair of plates 32 32, which are in turn jour- Secured to each end of each planetary shaft 31 is a planetary gear 33, which meshes with an adjacent stationary abutment-gear 34, secured to the inside of casing 110. Similarly mounted between each pair of arms 20 23 is a cam 35,

like the cams 30, each of said cams 35 being carried by a planetary shaft 36, journaledin a pair of plates 37 37, lournaled in turn on the shaft 22. Each p anetary shaft 36 is "provided at its ends with a planetary gear 38,

which gears mesh with the stationary gears 34. In the form shown in the drawings the gears 33 and 38 are one-third the diameter of the stationary gears 34, and therefore arranged at equal distances around the casing 10 are threeinlet-v'alve structures 40, each provided with a suitable inlet-valve 41, leading to an inlet-port 42, which leads into the annular chamber 12. The inlet-valves 41 may be omitted, if desired. For-med through the outer wall of each expansion-chamber is an inlet-port 43, which is extended along the outer face of the expansion-chamber, as at 43 so that While said ports 42 and 43 are themselves comparatively narrow yet the port43 43 will register with each inlet-port '42 during a considerable period, the inletport of each expansion-chamber coming successively into engagement with the inlet-ports of the casing as the expansion-chambers move around through the annular chamber 12. As a convenience in manufacturing and in order to permit easy access to each inletvalve I prefer to provide each inlet structure 40 with a shoulder 40, adapted to be held down tight against a correspondingshoulder on casing 10 by means of a set-screw 44, carried by an arm 45, supported upon a pin 46, supported from casing 10, the arrangement being such that by loosening the screw 44 the IO 51 the igniter 50 may 15 able series of contact members 60 5 same.

inlet-valve structure 40 may be sprung outof engagement with the casing and the inlet-valve readily examined.

Arranged adjacent each inlet-port 42 and 5 forward thereof is a suitable spar '-plug or other suitable igniting device 50, a port 51 being formed through the wall of casing 11), so that when the inlet-port 43 of the expansion-chamber comes into registry with port be available to ignite the combustible charge within said expansion-chamber. Forward of each igniter 51) is a multiple exhaust-port 52, through which the dead gases may be expelled. Any suitand timingcam 61 may be provided to cause the production of a proper spark at proper times in the spark-plugs 51.

Suitable wearing-blocks 70 may be arranged to take the sliding wear of the cams 30 and 35, if desired, and a suitable coolingjacket 62 may be provided, if desired. Secured to shaft 22 is a suitable fly-wheel 63.

Supposing the parts to be in the posit-ions illustrated in the drawings and a suitable gaseous fuel to be supplied to the several inlet-valve structures 40, the operation is as follows: A combustible charge having been introduced into the expansion-chamber 14, a

0 rotation of the ll vwheel and shaft 22 will cause a rotation of spider 21 in the same direction, so that its arms 20 will serve to drive the several expansion-chambers in a clock wise direction through the annular chamber 3 5 12. This movement of the arms 20 will withdraw them or tend to withdraw them from the cams and 35, so that the springs 25, acting upon the opposed arms 23' or 24, will cause said arms 23 and 24 to act upon the cams 30 and 35, so as to drive shafts 31 and 36 in an orbit around the axis of shaft 22, thus causing the pinions and 38 to roll upon their gears 34, so as to turn the cams 30 and 35 between the arms which straddle the Referring particularly to that cam .35 adacent piston 14, it will be seen that the planetary rotation of this cam in a clockwise direction simultaneous with its planetary revolution in the same direction will tend to retard the rotation of the arm 23, which carrics piston 14, thus permitting the combustion-chamber 14 to be driven over its piston 14, so as to compress the charge Within the expansion-ehamber 14 while the port 43 5 5 thereof approaching the adjacent ignitionport 51, at which time cam 35 will occupy that position between its adjacent arms 20 and 23 which in Fig. 1 is occupied by the cam 30 at the upper left-hand corner of-Fig. Supposing the expansion-chamber 17 to have received a charge in the manner ust described in connection with chamber 14, it will be seen that if the charge be now ignited within-chamber 17 the expansive force will 6 5 .act upon the piston 17, so as to drive its arm I 24 toward the arm 20, which carries combusl tion chamber 14, (any movement of the arm 1 20 which carries combustion-chamber 17 being prevented by reason of the fact that it at that time is in engagement with the smallest diameter of the cam 35 ,which lies between it l and the adjacent arm 23,) so that this force acting upon the said cam 30 tends to turn wise direction, thus tending to roll its pinions 33 on the stationary gears 34, and thus, by acting through cam 30 upon arms 20, tend to drive said arms in the same direction as their initial movement.

After the explosion takes place within any expansion-chamber it is translated toward the adjacent exhaust-port 52, and this translation causes the continued rotation of the corresponding cam 35 to such an extent as to again retard the rotative movement of the arms 23, thus permitting the expansionchamber 14 to be again driven over its piston 14, so as to expel the dead gases from chamber 14 through port 43 into the exhaust-port 52. Further rotative movement of the shaft 22 brings the extension 43 of port 43 into register with the next inlet-port 42, and continued rotation of the cam 35 35 causes a movement of arm 23 in excess of the rotative movement of the spider 21, (due to the action of the corresponding spring 25,) thus enlarging the expansion-chamber, so as to draw in a fresh charge of fuel. The operation is repeated in regular succession, each expansion-chamber receiving a fresh charge and permitting an explosion during each third of a revolution about the axis of shaft-20.
